Animal Pyn Rear Hub Guard

The Animal Pyn cassette hub guard protects the hub flange and spokes from grind damage by replacing the non-drive side hardware with a 7075 aluminum core and replaceable polycarbonate sleeve, which reduces drag for more predictable grinds. Designed to work with Animal Javelin hubs, but includes spacers to adapt to other hubs. (2.2 oz)
